AC current calibration
After the 700V AC at 1kHz point has been calibrated, the unit will prompt you for 100mA at
1kHz. Follow these steps for AC current calibration:
1. Connect the calibrator to the AMPS and INPUT LO terminals of the Model 2010 as
shown in Figure 2-3.
2. Perform the calibration steps summarized in Table 2-7. For each step:
Set the calibrator to the indicated current and frequency, and make sure the unit is in
operate.
Press ENTER to complete each calibration step.
Allow the unit to complete each step before continuing.
Setting calibration dates
At the end of the calibration procedure, the instrument will display the CALIBRATION
COMPLETE message. Press ENTER to continue, and the Model 2010 will prompt you to enter
the calibration date and the calibration due date. Set these dates as follows:
1. At the CAL DATE: mm/dd/yy prompt, use the left and right arrow keys and the range
keys to set the calibration date, and then press ENTER.
2. The unit will then prompt you to enter the next calibration due date with this prompt:
CAL NDUE: mm/dd/yy. Use the left and right arrow keys and the range keys to set the
calibration due date, and then press ENTER.
3. The unit will prompt you to save new calibration constants with this message: SAVE
CAL? YES. To save the new constants, press ENTER. If you do not want to save the new
constants, press the down range key to toggle to NO, and then press ENTER.
NOTE Calibration constants calculated during the current calibration procedure will not be
saved unless you choose the YES option. Previous calibration constants will be
retained if you select NO.
If an incorrect date is entered, the “INVALID DATE” message will be displayed. The
menu will remain until a valid date is entered.
